WHO Drug Dictionary (WHO-DD)

Introduction
# The WHO-DD is administered and licensed by the World Health Organization’s Uppsala Monitoring Center (UMC). The UMC collaborates with regulators, researchers and other professionals from healthcare and pharmaceutical industry in practice of pharmacovigilance.
#A drug dictionary proves useful when tabulating medication usage because it classifies the same medication, often known by different names, into a single name.
#For example – Tylenol, acetaminophen and paracetamol all refer to the same active ingredient, and WHO-DD uses the ingredient name paracetamol.
